The 6m Square tube used for the transition needs to be bent by machine to ensure correct radius. It’s recommended and easier to use the entire 6m when bending and then allow for a (6000mm – 561.2mm – 5027.18) = 411.62mm straight section at the bottom that needs to be cut of after the bending process.
The Transition Extension section can also be made-up of a normal transition and then addition of 1ft vert section (304.8mm). This might be easier when bending the 6m square tube as mentioned above.
If you like to build the coping before the ramp is finished you could use a coping jig as shown below to ensure that all the tags are in the correct place and correct angle. The coping is one of the most important aspects of the entire ramp and you should take extreme measures to ensure it 100% correct.
